It is well known that in ship turrets coniprising several guns, the ring of a lateral gun vwill cause a disaiming motion of the turret about its aXis of revolution. f p Y Shouldl it be desired to avoid this disaiining-motion, generally known under name of-turning it would be necessary to provide' for Aconsiderable strains upon the parts controlling the horizontalv aiming and Vconsequently to give them sizes which are exaggerated'relatvely to the stresses vwhich are to be transmitted duringthe aiming opera- A tion. e y One has thus been induced to arrange upon the driving means of the aimingv pinion, ap-A paratuses allowing'the turning while lim'-V iting the same to an acceptable value.'y v

The known apparatuses use l Ior attaining this result comprise:

l--Either a stress li generally la -friction one. Y

2-Or an elastic spring sleeve; e'

In the iirst case, after the disaiming,.pros

, duced by the iii-ing, the'pointermust return the turret to the direction of the aim. y

automaticallyl butina sudden', manner and after a certain numberlofoscillations. The stress exerted upon the pinion is'greaterv than in the first case,A asthesprings have to store a work similar toV the one which is absorbed by the friction of the first v'case and this work f is for the most part restoredto the turret..

The rotation of the Worm a is eiecteol 'i means of a. toothedwheel 2O Aconnected with f the Worm 10a by means of a sliding key. This Wheel itself is operated Vby a suitable inotor 17V through'the .medium of a pinion 18 and of a chain 19. Y l
